Enhance Tool Description

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

While no annotations are provided, the description explains the internal process ("examines the current tool's metadata, inspects its execute method signature") and generation capabilities, which gives some transparency into behavior. However, it lacks details on edge cases, failure modes, or what happens when the tool cannot complete the enhancement, leaving some room for improvement.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is composed of three well-structured sentences: the first introduces the tool's purpose, the second details usage scenarios, and the third describes the method. It is concise, informative, and avoids redundancy, effectively earning its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the lack of an output schema and annotations, the description sufficiently explains the tool's purpose, how it works, and what it produces. It covers the essential aspects needed for an agent to decide when to use it, though it could expand on potential limitations or errors. However, given the tool's complexity, it is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 100% schema description coverage, the parameters are well-documented in the schema itself, which is the baseline. The description doesn't add much semantic depth beyond the schema, but the schema is already clear on the parameters and their defaults, so the description doesn't need to repeat it, warranting the baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool "Analyzes existing MCP tools and enhances their descriptions" with specific verbs and resources. It distinguishes itself by mentioning specific actions like adding examples, clarifying parameters, and inspecting the execute method signature, which differentiates it from general documentation tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage context: "Use this tool when you need to improve or generate better documentation for a tool, such as adding examples or clarifying parameters." It clearly outlines the use cases and what the tool does (examines metadata, inspects execute method, generates documentation improvements), giving the agent clear guidance on when to apply it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
